Isotopes of an element will contain the same number of protons and electrons but will differ in the number of neutrons they contain. In other words, isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
Answer:
Leon
Explanation: all take up space and will have a mass to it.
The new concentration of the KCl solution after mixing 1 L new volume is 0.28 M.
<h3>How do we calculate the concentration?</h3>
Concentration in terms of molarity will be calculated by using the below equation as:
M₁V₁ = M₂V₂, where
M₁ = molarity of old KCl solution = 1.6 M
V₁ = volume of old KCl solution = 175 mL = 0.175 L
M₂ = molarity of new KCl solution = ?
V₂ = volume of new KCl solution = 1 L
On putting all these values on the above equation, we get
M₂ = (1.6)(0.175) / (1) = 0.28 M
Hence resultant concentration is 0.28 M.
